[Asterisk-video] Problem with calling out to 3G handset via ISDN

[Arnold P. Siboro]

Hi all,

I managed to build a system from libh324m that can receive calls from 3G
handset via ISDN BRI. However I could not make a call out to 3G handset
yet. I know some of you talked about how to make call out like this and
I think I have followed them, but please tell me which I missed.

Here is my extension.conf:
[sipout]
;exten => _X.,1,Dial(${GLOBAL(OUTGOING)}/${EXTEN})
;exten => _X.,2,h324m_gw(start at videocall)
;exten => _X.,2,h324m_call()
;exten => _X.,3,Hangup()

exten => _X.,1,Set(CHANNEL(transfercapability)=VIDEO)
exten => _X.,n,NoOp(transfer=${CHANNEL(transfercapability)})
exten => _X.,n,Set(CHANNEL(userinformationlayer1)=24)
exten => _X.,n,NoOp(ul1=${CHANNEL(userinformationlayer1)})
exten => _X.,n,Dial(${GLOBAL(OUTGOING)}/${EXTEN})
exten => _X.,n,h324m_call()

The SIP client tried to call 3G handset but failed with cause 96.
Here is the log where error appeared:
